Micro Force V+F3 Zoom Control

Description

The classic ergonomic design provides a rounded grip for comfortable all-day use and also offers a convenient attachment point for its mating Pan Arm adapter. Its housing, machined from solid aluminum alloy, protects the control from mechanical abuse and assures years of reliable operation. An integral camera run switch allows remote run/stop operation for both Film and Video cameras.

The V+F3 may also be used to provide the zoom function in conjunction with the FI+Z system as well as interface to professional Canon and Fujinon video lenses having 12 or 20 pin Hirose connectors.

The V+F3 unit operates over an input voltage range from 11 to 28 volts (30V max.). Polarity protection protects the electronics from improper power connection. A series of molded “Y” cables is used to interface with the zoom motor and the accessory connectors on most motion picture cameras.

Features

• Digital zoom speed display

• Adjustable motor direction

• Compatible with Preston FI+Z system

Specifications

1. Power Connections. The Micro Force may be powered using the following types of cables:

a. “Y” -Cables: (product series 1100) for specific film and video cameras. Micro Force power is drawn directly from the accessory socket on the camera.

b. Video Cables for Canon, Fujinon and Nikon lenses. Power is drawn from the 12 pin Hirose connector on the lens.

c. Zoom cables (series 4444, 4445) for use with the FI+Z system.

d. Auxiliary power cables (product series 1128-1130) may be used in conjunction with “Y” cables to power the control directly from a battery.

2. Power requirements.

The Micro Force operates over a voltage range of 11 – 30 VDC (max). Idle current is 55mA at 24 VDC or 95mA at 12VDC. The maximum current drawn under stalled motor conditions is 1.2A @ 24V (typ.) or 2.4A at 12V. The actual current requirement is proportional to the operating torque and the current limit set on the circuit board.

3. Control functions.

a. The Maximum zoom speed/ Sensitivity control is located at the bottom of the control. The adjustment range is from 00 to 99 in the digital display, corresponding 8 turns of the knob.

b. The zoom speed and direction is controlled by applying finger pressure to the red joystick knob either towards the top or bottom of the control.

b. The Direction switch reverses the motor rotation.

c. The Camera Run switch has 3 positions; Center Off, Toggle On (away from the joystick) and Momentary On (towards the joystick). The Toggle On position is for cameras requiring a continuous signal to run (i.e. Arri 12V, Panavision, Aaton), while the Momentary On is for cameras requiring a short pulse to change from run to stop (i.e. Arri 24V, Moviecam, Sony ).

d. The Zap switch sets the control to maximum speed. Pressing this momentary switch overrides the zoom speed setting, allowing the lens to be returned quickly to a desired position.

e. The Servo/Manual switch is placed in the manual position to allow the zoom ring of the lens to be driven manually.
